QUESTION: How can you adjust your APC polishing process to modify characteristics of the geometry and achieve consistent accuracy?
ANSWER:
APC polishing issues could derive from problems with mechanics (materials or equipment) or the polishing process itself. When developing a polishing process, the initial goal is to achieve consistency in geometry results (namely Radius, Angle/Apex, and Key Error), regardless of values (passing or failing of any specifications).
If you don’t see consistent results, it’s likely the variation is due to mechanical/equipment problems such as worn polishing fixtures, uneven rubber pad hardness, etc. After achieving result stability, it’s a simple matter to make process adjustments (namely pressure, rubber pad hardness, film abrasive size) to achieve desired results.
